Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The DA7283-01FV2 is a linear resonant actuator (LRA) haptic driver that provides automatic closed-loop LRA resonant frequency tracking. This function ensures the consistency of LRA production tolerances, operating temperatures, aging and mechanical coupling. The DA7283-01FV2 can drive LRA motors within its supported range without any programming and will automatically lock to the correct LRA resonant frequency without providing any actuator information to the device.

Main features

■ LRA driving capability

■ No equipment programming required

■ Three GPI pins for triggering clicks and complex modes at two driver levels

■ Automatic LRA resonant frequency tracking

■ Ultra-low power consumption, IQ = 5 nA, when the device is disabled

■ Low latency (0.75 ms) GPI wakes up from the low-power idle state, IQ = 0.68 μA

■ Differential PWM output drive

■ Edge rate control for EMI suppression

■ Current-driven system, providing constant actuator power

■ Automatic short-circuit protection

■ Automatic over-temperature protection

■ Automatic under-voltage locking protection

■ Automatic haptic playback timeout when the host disappears

■ Supply monitoring and automatic output limits

Application field

DA7283-01FV2 is mainly applied in motor drives, haptic feedback systems and motion control modules in industrial automation.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
